WebThe Si isotope fractionation in the Andean tributaries and the Amazon main stem can be explained by clay formation and follow either a Rayleigh or a batch equilibrium fractionation model. Our results also suggest that the formation of 2:1 clays induces a fractionation factor similar to that of kaolinite formation. WebThe Rayleigh fractionation model is first deduced by the principle of dynamic reaction, which indicates that Rayleigh fractionation can be explained by dynamic characteristics …
